Question

7. A cargo train covers 375 km in 15 hours. Find: b) time taken to travel 770 km.​

Answer 1

30.8 or 30 hours and 48 mins

Explanation:

375 km > 15 Hours

Divide 375 and 15, equals to 25.

So, to proof that 375 is equals to 15 hours, divide 375 and 25 then you will get the answer 15. :)

Now, divide 770 and 25 to get the time taken to travel 770km.

And the answer is 30.8 hrs or... 30hrs and 48mins

Answer 2

30 hours 48 minutes

Explanation:

Using the relationship

average speed =
`(distance)/(time)` =
`(375)/(15)` = 25 Km / hour

Then

time =
`(distance)/(speed)` =
`(770)/(25)` = 30.8 hours = 30 hours 48 minutes
